Searching NSMenuItem inside NSMenu recursively - cocoa

Question

The method itemWithTitle locates a menu item within a NSMenu. However it looks only inside the first level. I cannot find a ready-to-use method that will do the same job recursively by searching inside all the nested submenus. Or, somehow equivalently, a function that swipes NSmenu's recursively.
It looks quite incredible to me that such a thing would not exist. Maybe there is some function not directly related to NSMenu that can come in handy?

Answer 1

Ok, since I really need to do this clumsy workaround for a number of specific reasons (beyond the scope of this post, and quite uninteresting anyway) I ended up coding it myself.
Here is the snippet:
NSMenuItem * mitem;
while (mitem) { // loop over all menu items contained in any submenu, subsubmenu, etc.
// do something with mitem ....
mitem = next_menu_item(mitem);
}
which is powered by the functions:
NSMenuItem * goto_submenu(NSMenuItem * mitem){
NSMenu * submen = [mitem submenu];
if (submen && [[submen title] isNotEqualTo:#""] && [submen numberOfItems])
return goto_submenu([submen itemAtIndex:0]);
return mitem;
};
NSMenuItem * next_menu_item(NSMenuItem * mitem){
NSMenu * menu = [mitem menu];
if ([menu indexOfItem:mitem]==([menu numberOfItems]-1)) //if is last item in submenu go to parent item
return [mitem parentItem];
return goto_submenu([menu itemAtIndex:([menu indexOfItem:mitem]+1)]);
};

for (NSMenuItem *item in self.itemArray) {
if ([item.title isEqualToString:title]) {
return item;
} else if (item.submenu) {
NSMenuItem *result = [item.submenu itemWithTitle:title recursive:recursive];

return result;

}
}
return nil;
} else {

}
}
- (NSMenuItem *)itemWithTag:(NSInteger)tag recursive:(BOOL)recursive {

return item;
